Hi, I have two questions 1) How can I convert a raw miniDV file to ogg? I have made a continuation to the conference I organised two years ago on gravitational waves Astrophysics and Relativity and I have a lot of miniDVs to be converted to ogg. I think I have seen the information before but, after looking for some one hour, I have given up. And, by the way, do you know how to dowload the file

Hi everyone, I face a problem trying to encode a mkv file into theora using directshow filters I have a mkv file containing only video encoded in YUY2. I use the DirectShowNet Lib V2.1 ( <http://sourceforge.net/projects/directshownet/files/> http://sourceforge.net/projects/directshownet/files/) I use the matroska splitter directshow filter v1.0.2.9 (

Both MPEG-4 File Format (mp4) and Matroska (mkv) have an interesting format for lyrics and subtitles. Since these container formats can contain multiple contain streams, lyrics or subtitles are just another "stream" interleaved with the rest of the data. They are synchronized by having timestamps like any other stream. The payload is just text data. If you don't care about

Hi all, I just did a brief test with 3 different codec combinations: 1) ffmpeg sorenson/flv, mp3 audio in flv container 2) ffmpeg h264/vorbis audio/matroska 3) ogg/theora/vorbis using encoder_example Here are the results: 10721201 2010-10-16 14:46 origem1.flv 20731108 2010-09-13 23:04 origem1.mkv 33101703 2010-10-03 11:24 origem1.ogv as you can see, flv wins hands down, and it doesn't look

Hi all, Xiph aims at developing open-standards media formats. Though xiph.org tells about vorbis/theora/flac/speex, nothing is mentioned about container to use (that is ogg/ogm). I have a few questions Is there a difference between ogg and ogm? I guess its only the extension that is different and everything else is same. Some tools (like ogmtools) are available to create ogm files. What is

I tried to encode two minutes from an AVI DV file 720x480: ffmpeg latest release produces a FLV 320x240 25fps 360k video 40k audio in about 45 sec. ffmpeg latest release produces an OGG 320x240 25fps 360k video 40k audio in about 1:20 sec. ffmpeg2theora the same in about 2 minutes or more. The FLV quality it's quite good, some dropped frames maybe. I was wondering to know if ffmpeg team

Hallo again! Some month ago we discussed about the Vorbis Comment Chapter Extension: http://wiki.xiph.org/Chapter_Extension I got some critics about this specification, especially from the VLC developers: see https://trac.videolan.org/vlc/ticket/6895 Some parts of it: <cite> This specification allows holes between chapters and allows overlapping chapters... And does not explain what to

http://www.matroska.org/ I just found out about this and I think it looks like a great idea. I figured some on this list would be interested. Also, speaking now without having reviewed matroska in detail, nor being involved in Ogg/Vorbis: Perhaps it would be a viable alternative for the Ogg format for Theora if nothing else. I read about the .ogg format a while back, and while I have no

Hi, I haven't seen any information about Lyrics in the documentation and mail archives, so I guess the answer... but may be I've missed something... Does flac support lyrics? Regards, J?r?me

Hi, I have multiple ogg/theora files, with different bitrate. That is the big problem, because I want to broadcast them using ezstream/icecast and the connection between ezstream and icecast is always lost when switching between files. They have the same resolution but different quality. Is there a tool to concatenate/normalize several files to a big homogeneous one? -- A powerfull GroupWare,

Is there a program currently available that will correctly mux a52/ac3 streams and theora streams into an ogg container? I've tried oggzmerge, and it will mux ac3 into ogm and correctly create a new ogm from an existing theora file, but it doesn't seem to put the two together correctly.

Hi everyone, I have been using vorbis for ages as audio codec for archiving movies and I have always been happy with it, but now I have been thinking about two things: I) Multi-channel Up until now I mostly encoded to stereo; now I am thinking of encoding more movies to 4.0 or 5.1. I heard that vorbis does not optimize for channels > 2, i.e. that 6 channels is just stereo*3. AAC is

Hello, I'm looking into storing FLAC audio in Matroska and I have a few questions. 1. Can I use libflac to extract the compressed frames? Or will I need to write up a simple file parser? 2. What is required to decode the frames? From the docs I understand that you need the FRAME and you may need the METADATA_BLOCK. Thanks, Jory Stone jcsston@toughguy.net Matroska, the new,

Hello, You guys might want to join this discussion. (And maybe some others too.) On the WhatWG mailing list, there's been a fury of e-mails about adding a <video> element to HTML5. They're talking about codecs and containers now. It might be helpful to have your representatives there. And help shape things. See ya ---------- Forwarded message ---------- From: Dave Singer

First, Thank you for your answers. I using the following code to try simply decode a flac file and write the decoded data raw PCM file. The resulting file is just noise and pops, so is the decoded data in a different format than PCM? struct flacData { FILE *inputFile; FILE *outputFile; char *filename; }; FLAC__StreamDecoderReadStatus flac_DecoderReadCallback(const FLAC__StreamDecoder
